RE: [css3-background] Where we are with Blur value discussion

Check, thanks. Then I'm not sure I understand how Aryeh knows Opera is correct. Note that I'm
not saying he's wrong; I'm saying *I* don't get it :)

And it sounds like we already have some amount of fail for authors. Although that may
also be a reflection of my blind spots.

Not exactly.  SVG takes a number of stdevs as input.  <canvas> takes roughly twice the number of stdevs, with a different scaling factor above and below 4stdev.  CSS takes a number with absolutely no defined meaning right now, though in some cases it might be treated similar to how <canvas> treats its input.
